Abstract:
A process is for laser-welding resinous members, and includes the steps of overlapping a transparent resinous member (3) on an absorptive resinous material (4), and irradiating the transparent resinous member with a laser beam (1), thereby welding an interface between the transparent resinous member (3) and the absorptive resinous member (4) as a strip shape, wherein the energy of the laser beam (1) acting on a side of a major-curvature-radius curved part of the strip-shaped welded interface and the energy of the laser beam acting on a side of a minor-curvature-radius curved part thereof are averaged.
